Ive heard alot of talk about people running BPV's that vent atmospherically. Is there any difference between this and a BOV asides their original intended purposes? Is it as simple as taking my stock BPV and disconnecting the exhaust side hose from it to allow for atmospheric venting?

I guess re-circ side would be a better term to use, but yea, are there any detailed directions on this that anyone knows up? I wouldnt imagine you would want to plug up the intake side as well but I really dont know how this whole thing works, just seen people saying they have a stock BPV venting atmospherically

Eric P had some info on his site about it a while back but if I remember correctly it was pretty vague.

well the ghetto way (and it sounds like crap i did it while waiting for my hks to get here) is to just unhook the side that goes into the turbo intake and plug the hole on the turbo intake so it just vents the air to the atmo...if yuo do any tuning tho you will overpower the stock bpv

You can do what saabkid says, but switch the orientation of the bpv. I've got the forge in my 9k oriented the opposite way of the factory one and plumbed back into the intake...yes it works...yes it sounds different.

"2 pics of 9000 engine bay, normally the round part of the bpv would
face the front of the car, not up like shown in pics"

Now I understand, the visual definatly helped; the smaller of the vacuum lines which is now facing up, usually faces foward, so the peice facing downwards is usually the part that comes off the delivery pipe, correct?

Exactly. Valve works just fine this way...all you'd have to do is remove that bottom hose and you'd kinda have a pull type bov much like the hks one...which is kinda what the Forge sounds like plumbed this way on my car. The 9k and ng900/9-3 have the same stock bpv...so I think you can probably figure it out on your car from the pics.
